Arc Abrasives 71-30452 Predator PSA Discs are 6 Inch in diameter and deliver a fast cut with minimal loading. The technical grain combination of Predator discs easily performs at a 3-to-1 cut rate over standard aluminum oxide and zirconia alumina discs. The PSA (pressure-sensitive adhesive) securely holds the disc to the pad or platen and can easily be removed after the disc is finished. The discs don't leave residue on the pad or platen to ensure an even grinding surface and secure adhesion with the next disc. Predator PSA discs can control heat and extend cut with their proprietary combination of self-sharpening grains. These discs are ideal for mild steel and are a cost-effective alternative to full ceramic materials. 50 Grit. Pack of 50 discs.
